In an environment where natural sand and gravel resources are scarce and mining is restricted, the finished product of "machine-made sand" has a good grain shape, is controllable, and has a large profit margin. It can replace natural sand for various project constructions, but what kind of stone is used as raw material for machine-made sand? ?


What kind of stone is used for machine-made sand?

What are the raw materials for machine-made sand? Generally, stones with high hardness (such as river pebbles, granite, quartz stone, basalt...), stones with medium hardness (such as coal gangue, limestone...) are used as raw materials, and weathered stones, construction waste (concrete blocks), mine tails Ores are also suitable for processing into machine-made sand. The strength and particle size of machine-made sand made of different stones are different. The following is a general introduction to several commonly used raw materials:
1. River pebble is a kind of machine-made sand raw material widely used and with good texture. It is a good substitute for natural sand in terms of strength, grain shape, and color.
2. Limestone is widely distributed in nature and is easy to obtain. It can be used as raw material for sand and gravel at the same time, and stone powder can also be reused.
3. Granite with high quartz content and low sulfide content is a good quality machine-made sand raw material, and the dust problem needs to be solved.
4. Coal gangue has a certain degree of hardness. Relevant data show that coal gangue accounts for 15-20% of coal production and is rich in reserves. Reusing stone as a resource can also effectively solve environmental pollution.
The use of machine-made sand instead of natural sand is often used in road construction, bridge repair, housing construction and other industries. As an important component of concrete structural materials, the quality can directly affect the quality and durability of the project, and it is also necessary to use the corresponding grade of sand materials, such as: coarse Sand above 0.5mm, medium sand 0.5-0.35mm, fine sand 0.35-0.25mm.

Machine-made sand production process

Machine-made sand production line equipment configuration: feeder + jaw crusher (coarse crushing) + impact crusher (secondary crushing, secondary crushing) + sand making machine + vibrating screen + sand washing machine + conveyor;
cone crusher
impact crusher
1. The specific length and position of the conveyor can be determined according to the actual site conditions;
2. You can choose whether to use secondary crushing equipment according to the material characteristics, feed particle size, output, etc., and in order to meet the different processing needs of customers, you can configure cone crushers and dust removal devices. Cone crushers can handle stones with higher hardness , Durable wearing parts, such as river pebbles, granite... Increase profits for customers.
